Toxicology studies in laboratory animals describe potential health effects from varying levels of exposure to a chemical and identify the dose level at which no effects are observed. Only uses for which the exposure is well below levels that cause no effects in animal testing are considered acceptable for registration. As such, sex and gender are taken into account in the risk assessment. The dose levels used to assess risks are selected to protect the most sensitive human population (for example, children and nursing mothers). the levels to which people may be exposed.the levels at which no health effects occur and. When assessing health risks, two key factors are considered: Potential exposure to paclobutrazol may occur through the diet (drinking water only), when handling and applying the end-use product, or when entering an area that has been treated with the product. Trimmit plant growth regulator, containing paclobutrazol, is unlikely to affect your health when used accordingly to proposed label directions. Health considerations Can approved uses of paclobutrazol affect human health? It is absorbed by plant roots and translocated to the growing tissues. Paclobutrazol is a plant growth regulator which reduces internode growth, resulting in shorter and stouter stems. Footnote 3 Health Canada will then publish a Registration Decision Footnote 4 on paclobutrazol and Trimmit, which will include the decision, the reasons for it, a summary of comments received on the proposed registration decision and Health Canada's response to these comments.įor more details on the information presented in this summary, please refer to the Science evaluation of PRD2023-10. For more information on how the Health Canada regulates pesticides, the assessment process and risk-reduction programs, please visit the Pesticides section of the Canada.ca website.īefore making a final registration decision on paclobutrazol and Trimmit, Health Canada's PMRA will consider any comments received from the public in response to PRD2023-10. These methods and policies also consider the nature of the effects observed and the uncertainties when predicting the impact of pesticides. They also consider the unique characteristics of organisms in the environment. These methods consider the unique characteristics of sensitive subpopulations in humans (for example, children). To reach its decisions, Health Canada's PMRA applies modern, rigorous risk-assessment methods and policies. Conditions of registration may include precautionary measures on the product label to further reduce risk. The Act also requires that products have value Footnote 2 when used according to the label directions. Health or environmental risk is considered acceptable Footnote 1 if there is reasonable certainty that no harm to human health, future generations or the environment will result from use or exposure to the product under its proposed conditions of registration. The key objective of the Pest Control Products Act is to prevent unacceptable risks to individuals and the environment from the use of pest control products. What does Health Canada consider when making a registration decision? This summary describes the key points of the evaluation, while the Science evaluation of Proposed Registration Decision PRD2023-10, Paclobutrazol and Trimmit provides detailed technical information on the human health, environmental and value assessments of paclobutrazol and Trimmit. For details, see Proposed Re-evaluation Decision PRVD2013-04, Paclobutrazol, and Re-evaluation Decision RVD2014-06, Paclobutrazol.Īn evaluation of available scientific information found that, under the approved conditions of use, the health and environmental risks and the value of the pest control products are acceptable. Paclobutrazol is currently registered as a plant growth regulator for use on container grown ornamental bedding plants and plugs in greenhouses. Health Canada's Pest Management Regulatory Agency (PMRA), under the authority of the Pest Control Products Act, is proposing registration for the sale and use of Paclobutrazol Technical and Trimmit, containing the technical grade active ingredient paclobutrazol, for use on turfgrass on golf courses to slow the growth of turfgrass and suppress Poa annua.
